CONFECTIONERY MACHINERY. I

Application led February 27, 1925. Serial No. 12,091.

other suitable filling completely enclosed in an as even as possiblelayer or coating of chocolate. l,

In the present state of the art the first 7 thing in manufacturing suchsweets is to partly ll the moulds, by hand or by machine, Withsemieliquid chocolate and then to place in each recess or cavity of themould the corresponding cream filling, this operation being done withthe hand, by guess, and therefore most unevenly; the next thing is tocast over the surface a new layer of chocolate which covers the creamfilling, and this la er 0r coating is evened either by hand w1th aspecial knife or by machinery with a scraper under which the moulds aresuccessively fed. Results of such a method can not but be veryimperfect. The object of` my invention is to provide a cream or suchlike vfilling device that will overcome the above explained defects andmay be either hand or machine operated according to the type of mouldingmachine to which it is applied.

My device can be also advantageously applied to hand moulding byconfectioners unequipped with a power-driven -moulding machine.

In order to make myv lmachine more clearly understood I haveillustrated, as eX- amples, embodiments thereof in and by drawingsappended hereto and wherein:

Figure l is a plan view of a hand-operated form of filling device; 45Figure 2 is a vertical sectional view on line A-B of Figurel;

Figure 3 is a vertical section on line C-D and Figure 4: a section online E-F of the same figure;

Fi re 6 is a part-sectional side elevation of Figure 5;

sweetmeats must be made with a cream or` Figures 7 and 8 showmodifications of th arrangement of the fingers. y In all the figures thesamereference letters and numerals denote the same parts.

In principle, my device is composed of a metal plate l carrying a seriesof fingers 3 registering with the cavities of the mould 2 and suitablyshaped according to the cream fillings to be inserted. l

I will suppose, for instance, that I have to make a most popularsweetmeat, the cream-filled chocolate bar, that the mould 2 e comprisessiX cavities or recesses (these may, .of course, be any 1n number) andthat what is required is to force fillings 11 two millimeters down belowthe top level of the kmould. Plate. 1 willthencarry six series offingers3, suitably spaced and inclinedin order to maintain rigid the creamfilling 11, which is very frail in itself, by engaging several points ofits surface While avoid-1 ing transverse breaking. l.

I might, of course, have but a single Vfinger per recess, and cause thesaid finger to bear on the whole surfaceof the cream fill ing, but thismethod, which I reserve the right to employ for certain articles, is notpractical for light and long fillings because it involves the risk thatthe latter may be lifted through adherence.

Fingers 3 may also be set lengthwise in the case of a very long and thinbarv (Fig-v ure 7). Y

Figure 8 shows another modification, the fingers being in this casecylindrical and distributed over the whole surface of a speciallyshapedfilling.

In a general Way, `the setting of the fingers is to be varied accordingto the kid of confections to be made. Y

The above-mentioned plate l is secured by screws or any lother means toa metal box 6, preferably made of aluminum, containing a heatingelectric resistance 7 of any sort.

8 is an asbestos sheetkconcentrating the heat on the bottom and, throughthe conductivity of the metal, on the fingers 3 which become sufcientlyheated to keep liquid the chocolatewith which they are in contact ateach stroke. This heating is the essentially `characteristic featureofiny invention.

Were themfingers pv, cold theyY` would. soon get clogged with chilledchocolate, thereby seriously interfering with :the feven 1depositing of`the cream fillings.

9 is a metaly cover fitted with a handle 10 for operating the s device,iwhieh, .for V.greater convenience and in order to avoid fatiguing theoperators, is kept suspended by sa counterpoise 12 suiiiciently heavy toreturn it to initial position after A:each fdown `VAor working stroke. y

This result is easilyobtained by suitably proportioniug the ratio of the teeth of gears and46 and suitably setting the latter respecting the crank disk 22.

The moulds, always continuing to travel, pass 'under a scraper 42 Whichspreads over the bared fillings the chocolate that is forced up inconsequence of the driving in of the fillings. The moulds are thenautomatically shifted to a conveyorband 43 Whereon they are slightlypatted, either by an ordinary patting machine or by a vibrating plate ofany kind.

This operation glazes the surface of the confections Which arefinallycooled automatically in an adjacent ejecting mechanism, removed from themoulds and packed.
